Workshop Website

The workshop wants to bring together young researchers actively involved in the activities of the Observational Science Board (OSB), Instrumental Science Board (ISB) and Site Characterization Board (SCB) of the Einstein Telescope. Leaving plenty of room for discussions, it will be a great occasion to share research and ideas, start projects, learn about new topics, and build collaborations.

It does not matter whether you like cosmology or pulsars, individual sources or backgrounds, data analysis, cryogenics, quantum noise reduction, or novel sensing and control systems … if you are young and interested in ET science, this is the right place!

After an opening session on the broad activities of ET ISB, OSB and SCB, the workshop is organized as a series of parallel sessions between OSB and ISB, each featuring two talks by expert early career researcher, laying the ground on the topics of relevance for each division, followed by ample room for discussion.

As additional information for all the ET enthusiasts: there is another workshop, the Einstein Telescope Research Infrastructure: Challenges and Long-Term Sustainability workshop, to be held in Rome at Sapienza University on February 16–17.

Registration fee is 85 CHF and includes coffee breaks and an evening aperitif at CERN on 21 April. We encourage participants to book accommodation at the CERN hostel. The rate is 62 CHF for a single room with bathroom.

Workshp Website

In recent years, the modelling of gravitational wave sources has become a cornerstone of theoretical and numerical relativity. Multiple communities—working with distinct formalisms such as Self-Force, Effective One Body (EOB), Effective Field Theory (EFT) and post-Newtonian approximations—have developed powerful tools to describe the two-body problem with increasing precision. Each of these approaches is advanced enough to come with its own set of language, notation, conceptual framework, and computational tools.

The workshop aims to bridge this gap and bring these communities closer together. This will be done by providing a mix of beginner friendly lectures, hands on coding sessions, plenary overviews together with state of the art research talks for each of the fields.

Workshp Website

The workshop, to be hosted at the new German Centre for Astrophysics (DZA) in June 2026, builds on the highly successful Kavli-IAU Global Coordination Workshop series. This will bring together approximately 50 astronomers and astrophysicists from around the world to discuss the global considerations of time-domain astronomy and multimessenger astrophysics. The drivers for these areas over the next decade will be large, international projects which require prompt and coordinated follow-up of new astronomical discoveries that may disappear in just a few days, or even sooner. 

The primary objectives of the workshop will be to 1) define and prioritise the outstanding scientific questions that require coordinated, multi-wavelength follow-up in this time period, and 2) produce a series of recommendations to be implemented by the astronomical community in order to achieve these scientific goals. It will bring together key representatives from the major projects involved in these areas as well as the broader astronomical community around the globe (including theorists, instrumentalists, and observers).

Recommendations will be translated into a report titled “An Updated RoadMap for Global Coordination in the Time-Domain and Multi-Messenger Eras”.

This workshop aims to bring together leading researchers and industry professionals to address sustainability challenges and innovative solutions for this large underground infrastructure. Discussions will span the entire project lifecycle, from initial design to decommissioning, with a dedicated session fostering collaboration opportunities for industrial partners. 

Sustainability has become a top priority across industries, fueling global initiatives to conserve resources, reduce carbon emissions, and mitigate environmental impacts while promoting efficiency and collaboration throughout product life cycles. The development of large-scale underground infrastructures, such as the Einstein Telescope, requires an integrated and forward-thinking approach to ensure sustainability is embedded across every phase of its lifecycle.
This research-industry workshop seeks to bring together leading experts and industry actors to discuss sustainability challenges linked to large-scale underground scientific infrastructures. Using the Einstein Telescope project as a model case, the event will foster innovative discussions and collaborative solutions to address these critical issues.

The program will facilitate the examination and the discussion of sustainability approaches applicable throughout the complete project lifecycle:

• Design Phase: Integration of sustainability principles in initial conceptualization and planning
• Construction Phase: Implementing eco-friendly building techniques and material selection and reuse strategies.
• Operational Phase: Minimizing resource consumption and environmental impact
• Decommissioning Phase: Evaluation of responsible site restoration approaches.

The workshop will include a dedicated session, for potential industrial collaborators, to explore partnership opportunities in this cutting-edge scientific endeavor, to examine relevant aspects of a sustainable procurement strategy and to have the opportunities of scheduling 1:1 meetings with project experts in “Affreschi” Room adjacent to the main workshop room.

This Workshop is organized in the context of the activities carried out by Workpackages 7 and 9, of the Einstein Telescope Preparatory Phase (ET_PP) EU funded program.

General Relativity (GR) perfectly describes a variety of phenomena in gravity at energy scales much less than the Planck mass. However, this theory calls for an ultraviolet (UV) completion at higher energies. 

Various approaches have been developed in this direction in the past decades, including (but not limited to) string theory, which naturally contains the limit of GR. The low-energy effective field theory (EFT) of GR can also have a UV completion which is formulated as a field theory, perturbatively including higher curvature operators or non- perturbatively with an asymptotically safe fixed point. Formulation of new methods, especially working for gravity in the non-perturbative regime, requires more exchanges between the scientific communities that used to be separated. We believe that cross-team discussions will lead to significant progress in understanding the self-consistency and potential phenomenological implications of UV complete descriptions of gravity.

The goal of the workshop is to bring together the experts working on different UV complete approaches to quantum gravity, from string theory to various perturbative and non-perturbative approaches. Given the promising opportunity to probe quantum gravity effects in the very early Universe with future CMB and gravitational wave experiments, we expect the in-depth discussions on predictions and self-consistency of low- energy effective theories on top of cosmological backgrounds.

The meeting will be mainly focused on the following directions:

• Non-perturbative methods, in application to quantum gravity, such as string theory, amplitudes bootstrap, functional renormalisation group, loop quantum gravity, etc.
• Quantum gravity effects in the early Universe: inflation, cosmological correlators, non-gaussianities, gravitational waves.
• EFT of gravity in connection with cosmology and Black Holes.
• other related topics.

Astrophysical black holes can be entirely described by just two properties: their mass and their spin. While masses of black holes have been extensively studied, black hole spin remains poorly understood. This is because spin is both much more difficult to observe and more complex to model. Nevertheless, spin is no less integral to the evolution of massive black holes over time, and the role they play in shaping their host galaxies.

This workshop is a chance to discuss the nature and evolution of massive black hole spin from both an observational and theoretical point of view. It aims to bring together the theoretical and observational communities to advance our collective understanding of black hole spin evolution. In this workshop we will focus on the evolution of the massive black hole spin distribution across cosmic time, as informed by analytic models, numerical simulations as well as multi-frequency and multi-messenger observations.  Theoretical sessions will cover simulations and analytic models, from accretion-disc scale phenomena via the impact of binaries and inspiral on massive black hole spin to a discussion on what we can learn from galaxy scale and cosmological simulations on the spin distribution of massive black holes. Observation-focused sessions will include gravitational waves, X-ray based and interferometry-based spin measurements, and those based on transient events. The goal of this workshop is to bring together theorists and observers to exchange state-of-the-art insights and guide future efforts to maximise the understanding of black hole spin across cosmic time.

Core questions include:

– When and where can we observe massive black hole spin?

– What can we learn about massive black hole spin from current theoretical and numerical efforts on different astrophysical scales?

– What observations do we need most to constrain models?

– Where should modelling efforts be focused to make the most of the existing and upcoming observational missions?

– What do we need to prepare to make the most of upcoming missions?
